Muhammad OWNED slaves whom he supposedly "freed"(as well as slept with) according to the sugarcoated fairytale
He slept with slaves?
If you're talking about one of his dark skinned wives whom he married after she had been widowed and was much older than him
If he was so pro slaves, why not incorporate it into the religion? Why give such a prestigious title of being the first "Muathan" In Islamic history to a "slave" (estaghfarallah) , why not give it to a "white" arab?
When you feeble minded knuckleheads stop giving color so much basis in life , liberation will ensue and you will realize that god loves all and preference is given based on actions, as stated EVERYWHERE in the Quran.
